I did find a thread but no answer : http://traxxas.com/forums/showthread...x-2218-on-7.4v
Simply as the title says can you run the 2218 LINK receiver on a higher voltage to take advantage of the new HV servos out there. I haven't tried but most receivers of old would run on less voltage, 4.8v is the norm for plane guys. A fully charged receiver pack is always over 6v for the first little bit of the run. If not 7.4 volts maybe somewhere in the middle (6.5-7.0V).
I have an adjustable BEC (MMP) and am shopping for some new servos.
